Abstract:
Methods, apparatuses and devices related to the manufacturing of compensation devices are provided. In some cases, an n/p-codoped layer is deposited for calibration purposes to minimize a net doping concentration. In other cases, alternatingly n- and p-doped layers are then deposited. In other embodiments, an n/p-codoped layer is deposited in a trench where n- and p-dopants have different diffusion behavior. To obtain different doping profiles, a heat treatment may be performed.
